Elliott YR steam turbines are among the most rugged

and reliable pieces of precision turbomachinery

available anywhere in the world. These master-

pieces of Elliott engineering and craftsmanship

serve thousands of customers continuously day and

night under conditions ranging from humid tropical

heat and rainfall to freezing icy tundra and snowfall.

Many YRs have been performing for decades. Day

after day, year after year.

Because of their flexibility in adapting to customer

needs and the available selection of different

models, YR turbines are found in a great diversity of

applications such as driving pumps, compressors,

fans, blowers, generators, sugar mill tandems, cane

shredders, paper machine lineshafts and other es-

sential production equipment.

YR turbine products are standardized, and Elliott

offers numerous models and accessory options to

satisfy the many customer turbine requirements. Be-

cause YRs are standardized and major components

are stocked, customers can expect prompt shipment

to site, avoiding lost production.

ellioTT MulTi YR TuRbine

For improved steam consump-tion, Elliott engineers designed the Multi-YR Turbine product line. This design combines the reliability and parts interchange-ability of our popular single-stage YR turbine with the power and efficiency of our traditional multistage turbines. Because the Multi-YR produces more horse-power without additional steam, it can be mounted in many areas where single-stage steam turbines are currently operating. Multi-YR turbines are available up to 10,000 hp (7500 kW).

Liner-Type Bearing

Shaft Seals

Self-Locating Rotor

• Easy to inspect• Easy to replace• Inexpensive

Doweled bearing caps are removed without disturbing other parts – including gov-ernor and linkage and are replaced without any adjusting. Bearing liners snap and lock in place no hand-scraping or fitting is required. To promote rapid heat transfer, bearings have a thin-wall steel shell with a bonded babbitt surface. A water jacket removes heat from the lubricating oil, and combined with air spaces at the bolting surfaces, insulates the oil from casing heat.

Bearing cases are sealed by rotating “air-turbulence” labyrinth seals that have both internal and external slingers. Lubrication is by oil rings and oil is supplied by a constant-level oiler.

Plugged openings are furnished for inspection of oil ring rotation, and for draining the water jacket and oil reservoir.

• Easy to inspect• Easy to replace

The casing seal glands (packing cases) are separate from and bolted to the casing except for the AYR. The carbon sealing rings are thus easily inspected or replaced by a single person; only the upper half of the gland is removed. The heavy casing cover, rotor, and lower half of the gland need not be disturbed.

Non-rusting Inconel springs hold the three segments of each ring firmly in place. Spring stops, locked in position by the cover, prevent the seals from rotating. The rings are sized by computer to assure proper clearance at shaft operating tempera-ture.

In the seal area, the shaft is spray coated with stainless steel to prevent corrosion and wear then ground to a mirror finish.

• No fitting• No clearance adjustment required

The rotor is always in perfect position without adjustment. A large single-row, anti-friction locating bearing (red arrow) fits against a machined shoulder on the turbine shaft and into a groove in the steam end bearing case. Numerically controlled machining of components makes shimming for positioning the rotor unnecessary. The bearing’s outer race has an anti-rotation band with a stop that is locked in place by the bearing case cover.

The dynamically balanced rotor has stainless steel blades with stainless steel shroud bands mounted in the high strength alloy steel disks. The latter are shrunk and keyed onto an annealed carbon steel shaft.

... No other single-stage turbine gives you all of these advantages QualiTY & FlexibiliTY
